public class PreferenceContext
extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer

Central configuration for OMERO properties from (in order):

• Any injected Properties instances
• Java System.getProperties()
• Any configured property files

As of OMERO 4.2, server configurations are not stored in Java's Preferences API but in an IceGrid xml file under etc/grid of the server installation. The properties are set in the config file on node startup, for example in var/master/servers/Blitz-0/config/config. When the Java process starts, Entry places the values in {#link System.getProperties().

Since:

3.0-Beta3

Constructor Detail

PreferenceContext

public PreferenceContext()

By default, configures this instance for PropertyPlaceholderConfigurer.SYSTEM_PROPERTIES_MODE_OVERRIDE as well as ignoring unfound resources.

Method Detail

postProcessBeanFactory

public void postProcessBeanFactory(org.springframework.beans.factory.config.ConfigurableListableBeanFactory bf)

Description copied from interface: org.springframework.beans.factory.config.BeanFactoryPostProcessor

Modify the application context's internal bean factory after its standard initialization. All bean definitions will have been loaded, but no beans will have been instantiated yet. This allows for overriding or adding properties even to eager-initializing beans.

Specified by:

postProcessBeanFactory in interface org.springframework.beans.factory.config.BeanFactoryPostProcessor

Overrides:

postProcessBeanFactory in class org.springframework.beans.factory.config.PropertyResourceConfigurer

Parameters:

bf - the bean factory used by the application context

getProperty

public String getProperty(String key)

Lookup method for getting access to the merged properties for this instance.

setProperty

public void setProperty(String key,
               String value)

With ticket:2214, preferences are no longer mutable. For that, we will need a python server which can update the XML file.

setPreferences

public void setPreferences(List<Preference> preferences)

resolveAlias

public String resolveAlias(String key)

getKeySet

public Set<String> getKeySet()

checkDatabase

public boolean checkDatabase(String key)

canRead

public boolean canRead(EventContext ec,
              String key)
